SPRING-BACK FOR ROAD-CARTS.

SPECIFICATION forming part of Letters Patent No. 427,088, dated May 6, 1890. I Application filed November 30, 1889. Serial No. 332,097. (No model.)

To all whom t may concern.-

Be it known that I, JOHN D. HOUGH, a citizen of the United States, residing at Lowville, in the county of Lewis 'and State of New York, have invented certain new and useful Improvements in Seat-Backs for Road-Carts; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and'use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in sprin g-backs for road carts; and it has for its object to simplify and cheapen the construction and to rendermore efficient and durable this class ot devices.

A further and more immediate object of the invention is to provide a spring-back for roadcarts in which it is rendered possible to quickly and easily adjust the tension of the spring when such adjustment may be either necessary or desirable.

To the above ends, and to such` others as the invention may pertain, the same consists in the peculiar construction, and in the novel combination, arrangement, and adaptation of parts, all as more i'ully hereinafter described, shown in the accompanying drawings, and then speciiically deiined in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part -of this specification, like letters of reference indicating like parts throughout the several views, and in which drawings- Figure l is a perspective view of a seatconstructed in accordance with my invention. Fig. 2 is a front view of the same.

Reference now being had to the details of the drawings by letter, Adesignates the bottom, B the back, and OO the arms of the seat.

D is a strip or bar of metal which is secured to the bottom of the seat and extends transversely across the same near its front edge. At points adjacent to its ends the said bar is bent or curved slightly downward and again extended in a horizontal plane to a short distance beyond the side edges of the seatbottom, as shown. Secured to the under side of the seat-bottom and extending a short distance in rear of the rear edge of the same, at substantially its longitudinal center, is a metallic strip E, and passed loosely through a hole in said strip near its free end is a vertical rod F, the upper end ot said rod being secured to a horizontal arm G secured to the seat-back.

H is a spiral spring which is sleeved upon the rod F, the ends of said spring having bearings against the extensions E and Gr, as shown.

The front ends of the arms of the seat are provided wit-h eyes or openin gs which` are adapted to be sleevedlooselyupon the rounded free ends of the strip D, and are held thereon and prevented from vertical displacement by means of nuts I, said ends being screwthreaded to receive the nuts'. l

The upper end of the rod F is screw-threaded for a considerable distance, and both above and below the point upon the rod at which it passes through the vertical opening in the arm G adj Listing-nuts J J are provided.

From the foregoing description the operation of the device will be readily understood. The position of the spring at the rear of the seat renders it readily accessible when it may be desired to repair or adjust it, and the tension may be readily adjusted, when desired, by means of the adjusting-nuts J, by the movement of which nuts the length of the vertical rod within the spring may be readily lengthened or shortened, as will be readily understood.

Having thus described my invention, what I claim to be new, and desire to secure by Let ters Patent, is-

l. In a seat for road-carts, the combination, with the seat-bottom, of the seat-back hinged thereto, a vertical rod secured at its-'upper end to an arm extending from the rear of the seat-back, its opposite end passed loosely through an opening in an arm extending rearwardly from the seatbottom, and a spring sleeved upon the rod between the arms, substantially as described.

IOO

2. The herein-described seat for road-carts,

the same comprising in combination a bottom,

a strip of metal extending transversely across the under side of the bottom, near its front 5 edge, the seat-arms sleeved at their' forward ends upon the extended ends of the transverse strip and their opposite ends secured to the seat-back, arms extending rearwardly from the seat back and bottom respectively, Io a vertical rod adj ust-ably secured at its upper end to the arm upon the seat-back and passed loosely through an opening formed in the arm upon the seat-bottom, and a spiral spring upon the rod, substantially as shown and described.

In testimony whereof Iafx my signature in presence of two Witnesses.
